Attachment 1 Kuparuk River Oil Pool 2018 Annual Reservoir Surveillance Report Summary of the Enhanced Recovery Project Enhanced Recovery Miscible water‐alternating‐gas (MWAG) was the main enhanced oil recovery (EOR) process for the Kuparuk Field in 2018. In September of 2018, NGL imports from Prudhoe Bay (PBU) were brought back into Kuparuk for the first time since 2014, which ultimately enabled MI injection into 15 different drillsites and 50 injector‐centered patterns. Kuparuk Field manufactures miscible injectant at two of its Central Processing Facilities (CPFs). Miscible injectant (MI) is manufactured by blending together produced lean gas and natural gas liquids (NGLs). Only indigenous NGLs were used for making MI prior to September of 2018 while both indigenous and PBU NGLs were used post imports re‐start in September, greatly expanding the available target MWAG drillsites. MWAG Small‐Scale EOR (SSEOR and SSEORX) Drillsites 1Y and 1A were not MI targets in 2018, but did have lean gas injection. Drillsite 2Z did have MI injection in five of its patterns, totaling an average 12‐month MI injection rate of ~0.3 mmscfd. Large‐Scale EOR (LSEOR) The original LSEOR drillsites include: 1F, 1G, 1Q, 1R, 2A, 2B, 2C, 2D, 2F, 2G, 2H, 2K, 2M, 2T, 2U, 2V, 2W and 3F. Of these drillsites, 2A, 2B, 2C, 2D, 2F, 2G, 2H, 2K, 2M, and 2T started receiving MI post PBU imports re‐start, summing up to an average 12‐month 2018 MI injection rate of 12 mmscfd. EOR Expansions Expansions to the original LSEOR occurred over multiple phases and now include drillsites 1B, 1C, 1D, 1E, 1L, 2S, 3B, 3G, 3H, 3O, 3Q and 3S. During 2018, the average 12‐month MI injection rate into drillsites 1B, 1C, 1D, 1E, and 2S was 51 mmscfd. IWAG Lean gas available after blending MI was injected into the field as immiscible water‐alternating‐gas (IWAG). The drillsites which received lean gas were: 3Q, 3O, 3S, 3G, 3F, 3B, 1Q, 1Y, 1A, 1F, and 1L. Prior to MI injection into CPF2 (pre‐PBU imports), drillsites 2A, 2M, 2T, 2H, 2G, 2F, 2C and 2Z also received lean gas in 2018.

There were 14 out of 17 injection surveys reported for the Kuparuk River Oil Pool to the AOGCC in 2018; data quality deemed unreliable for 3 injection surveys.

Attachment 1 Meltwater Oil Pool 2018 Annual Reservoir Surveillance Report Summary of EOR Project and Reservoir Management Summary Background In 2001, ConocoPhillips Alaska, Inc. (CPAI) received approvals for formation of the Meltwater Oil Pool in the Kuparuk River Unit, an Area Injection Order for Meltwater, expansion of the Kuparuk River Unit, and formation of the Meltwater Participating Area. The Meltwater Pool Rules and Area Injection Order were approved on August 1, 2001. The Unit Expansion and Participating area were approved effective June 1, 2001. The Area Injection Order was modified on January 29, 2013 and again on October 8, 2015. Miscible gas injection (MI) began in January 2002 and the miscible water-alternating gas (MWAG) process was implemented in May 2003. The Meltwater MWAG process used Kuparuk spec miscible injectant (MI) which was injected above the minimum miscibility pressure. In 2009 the water injection line to Meltwater was proactively shut-in due to internal corrosion and the field was converted to MI flood only. In July 2014, natural gas liquids (NGLs) imported from the Prudhoe Bay Field Central Gas Facility into the Greater Kuparuk Area ceased and the Meltwater field was subsequently converted to lean gas injection (LGI) only. In September 2018 NGL imports resumed and the field was returned to miscible injectant (MI) flood only after the first phase of injection line work was completed in November 2018. This period of MI only is expected to last until summer 2019 at which point the injection line will be fully converted to water injection, which is the service expected for the remainder of the field life. The Meltwater field currently has 19 total wells (11 producers and 8 injectors). See Attachment 9 for well locations. Progress of EOR Project Development activities in 2018 followed the plans described in the Pool Rules, Area Injection Order, Unit Expansion, and Participating Area (PA) applications. Below is a listing of the key events related to the Meltwater Pool and PA in 2018: 1.As of December 31 2018, A total of seven wells were shut in at Meltwater. Two producers (2P-443, 2P-451) and five injectors (2P-419, 2P-429, 2P-432, 2P-434, 2P-438). The producers are shut in for high GORs and/or low productivity and the injectors are shut in for causing high gas/oil ratios (GOR) in offset producers requiring periodic shut ins due to gas handling. Reservoir Management Summary Meltwater came on-line in November of 2001 and has cumulatively produced 20.0 million barrels of oil (MMBO), 3.7 million barrels of water (MMBW), and 64.4 billion standard cubic feet (BSCF) of gas by year- end 2018. MI began in 2002 with water injection beginning in 2003 (MWAG cycles). Cumulative injection through year-end 2018 at Meltwater was 25.2 MMBW and 89.4 BSCF of gas (57.2 BSCF of MI and 32.3 BSCF of lean gas). Water injection ceased in October 2009 when the water injection line had to be taken out of service due to operational constraints caused by areas of excessive under-deposit corrosion pitting. GKA Annual Surveillance Report Meltwater Oil Pool 71 Comparing the estimated performance of Meltwater on depletion and gas injection, it is more efficient to inject gas at Meltwater than other fields in the Greater Kuparuk Area. In addition, gas injection appears to give more support to injection wells due to its higher mobility. However, a gas only flood leads to increasing GORs. The GOR at Meltwater has been rising and will soon cause the wells to be uneconomic to produce. Therefore, CPAI plans to convert the flood at Meltwater to water. Currently all the injectors are being operated below the sandface injection pressure required by AIO21B. Cumulative I/W at Meltwater as of 12/31/2018 was 1.2. Instantaneous I/Ws were high in 2018 leading up to and during the injection line conversion work taking place in the fourth quarter. Once converted to water injection, the longterm strategy will be to operate at an instantaneous I/W of 1, however the primary control of water injection rate will be the 3,400 psi injection pressure limit.

Test separator backpressure corrections were applied to wells that experienced greater than 100 psi backpressure over header pressure. Correction to stock tank barrel conditions were made by applying Meltwater specific pressure corrections, derived from the PVT analysis of Meltwater North #1 crude oil samples, and API temperature corrections. Miscible gas was used for injection and gas lift at drillsite 2P through July 2014. From July 2014 forward, lean gas was used for injection and gas lift until November 2018 when NGL imports resumed and the drillsite was converted back to Miscible gas. For the wells that were on miscible gas lift during a well test, the metered liquid rates have been adjusted for the natural gas liquids associated with miscible gas lift. Production volumes were tracked through an automated production monitoring SCADA system (IP.21) utilizing meters that transmit data in real-time for monitoring. The 2018 Meltwater allocation factors by month are listed below.

Based upon the information gathered, and technical analyses completed to date, it is likely the initial migration of injected fluids out of the Bermuda interval was a result of a large pressure differential between injectors and producers. This pressure differential was exacerbated by low permeability and stratigraphic and/or structural discontinuities within the Bermuda interval. The Operator continues to monitor OA pressures, take OA fluid levels, and sample OA gas composition on a routine basis. There are currently no indications that injection has occurred out of the Bermuda interval in 2018. Gas sampling will be discontinued once water injection is implemented as it will no longer indicate a loss of containment. In addition, the extended bleed of the outer annulus of well 2P-431 is continuously monitored in an effort to deplete the source charging the outer annulus. GKA Annual Surveillance Report Meltwater Oil Pool 82 2018 IA and OA pressure trends for all wells are included in Attachment 7. Significant Studies in Progress This section is meant to include the documentation to satisfy Rule 9 Item E ‘assessment of fracture propagation into adjacent confining intervals’. 1. No new studies on the fracture propagation into adjacent confining intervals has been completed that has not previously been reported to the AOGCC. 2. A new Meltwater reservoir management plan was put in place in July 2012 and continued to serve as the reservoir management strategy through 2018. This reservoir strategy included imposing a well head injection pressure limit on Meltwater injectors. The sand face injection pressure limit of 3,400 psi imposed on Meltwater injectors is predicated upon FIT/LOT (Formation Integrity Test / Leak-off Test) data obtained from Meltwater wells with production casing set at the top of the Bermuda interval. Upon implementing the reservoir management strategy changes, production and reservoir data continued to be collected and shared with the AOGCC. The overall pressure decrease from the aforementioned bleed campaign is significant, as the OA pressures of all wells, with the exception of 2P-447, are below the new maximum allowable operating pressure of 1,000 psi per Area Injection Order 21B. During 2013 – 2018, four hour bleeds of all Meltwater outer annuli that had gas at surface were performed semi-annually as a method to monitor the change in recharge rate over time.

Opportunities could include coiled drilling sidetracks and/or producer to injector conversions. Pipeline Operations The DS2P water injection line (2PWI) remains out of service after extensive pitting damage was discovered throughout the line in 2009 by ILI tools. Detailed analysis of ILI and physical inspection data confirms that this line is suitable for PO service. The current DS2P produced oil line has a low average velocity and is monitored closely via several physical inspection locations. The 2PWI line will serve as a backup in the event the current PO line is taken out of service. The GI line has a suitable pressure rating for WI service and will therefore be used to supply the drillsite with water. A jumper will be placed at DS2N to connect the water injection source at 2N to the gas injection pipeline. The water will then be transferred to the original water injection header at DS2P for injection into the reservoir. In addition, a stream of water will be recycled directly from the injection line to the production line to keep the production line warm during winter months as production rates from Meltwater decline. Exploration/Delineation No further exploration work is currently planned for the Bermuda interval. Surveillance plans for 2019 In accordance with AIO21B Rule 9 Item I the following bullets are key to 2019 reservoir surveillance plans. • Keep reservoir injection pressures below 3,400 at all times. • Continuous monitoring of OA pressures through the SCADA system. • Semiannual bleeds of all wells up to 4 hours in length. • Monitoring of the 2P-431 bleed system. • Sampling of OA gas samples as needed, until Water Injection conversion completed. • OA Fluid Levels to be taken periodically.

Water injection was 4.1 MMBW over the same period. Cumulative oil, gas, and water production through year‐end 2018 were 20.6 million barrels of oil, 3.5 billion standard cubic feet of gas, and 99.6 MMBW, respectively. Cumulative water injection through year‐end 2018 was 113.5 MMBW. The cumulative year‐end 2018 injection‐withdrawal ratio, based on current formation volume factors, is estimated at 0.90 for Tabasco. Year‐end 2018 Tabasco well count (all at Kuparuk River Unit Drill Site 2T) was: Producers: 9 completed 3 online, 2 awaiting RWOs, 1 P&Ad, 1 conversion underway Injectors: 3 completed 2 online Well 2T‐204 had its perforations isolated with cement in 2013 due to low productivity, it is not economic to produce at this time. In 2018, two producers were offline due to high watercuts with the intention of converting one to injection and returning one to production. One producer was offline due to a stuck coiled tubing string from a packer leak repair job, and two producers came offline with broken motors. One injector was offline due to reservoir management. As of December 31, 2018 Tabasco oil pool was producing with three producers and two injectors online. Water breakthrough has occurred at all producers in the Tabasco Oil Pool. Production and injection logs, coupled with the structural positions and water breakthrough histories of the producers, suggest that the water production mechanism is dominated by gravity‐induced slumping and flow through high‐permeability facies.

Attachment 6 Tabasco Oil Pool 2018 Annual Reservoir Surveillance Report Results of Well Allocation A minimum of two well tests per month are conducted on production wells. Fluid samples are obtained on a regular basis, and water cut corrections are applied to well tests as required based on subsequent lab analysis. Generally, good agreement was observed for water cuts comparing phase dynamics and shakeout analysis. Production volumes are tracked through the IP.21 production monitoring SCADA system. In 2002, Tabasco switched from an allocation factor of 1.0 to floating production allocation factors. Tabasco 2018 production allocation factors were as follows: Month Oil Gas Water Jan-18 0.9139 0.9139 1.0527 Feb-18 0.8958 0.9084 1.0333 Mar-18 0.9389 0.9029 1.0292 Apr-18 0.9219 0.9145 1.0376 May-18 0.9231 0.9178 1.0315 Jun-18 0.8475 0.8375 0.9704 Jul-18 0.8344 0.8215 0.9601 Aug-18 0.9157 0.9177 1.0638 Sep-18 0.9008 0.9093 1.0594 Oct-18 0.9081 0.9004 1.0628 Nov-18 0.9051 0.9192 1.0490 Dec-18 0.8998 0.9202 1.0490 GKA Annual Surveillance Report Tabasco Oil Pool 107 Attachment 7 Tabasco Oil Pool 2018 Annual Reservoir Surveillance Report Development Plans and Operational Review Tabasco injection-withdrawal ratios are monitored to maintain an instantaneous value of approximately 1.0. Adjustments to injection and/or production rates are made to achieve this in order to maintain pressure support for the Tabasco Reservoir and keep gas in solution. The 2018 injection strategy continued replacing voidage by splitting water injection between 2T-201 and 2T-217A. In November of 2014 chemical tracers were injected into the two in-service injectors, 2T-201 and 2T-217A. From 2015 to 2017 all active producers were sampled on a regular basis for the presence of these tracers. The concentration and duration of the chemical tracer breakthrough was used to evaluate heterogeneities within the Tabasco reservoir, and found the majority of current sweep to be taking place in the periphery of the field, within close proximity of the two active injectors. This finding was key to the proposal to convert the 2T-209 from production to injection. The 2T-209 producer watered out and was suspended with a plug in 2012. It is currently in the process of being converted into an injector in the central canyon area. This conversion is premised to provide more pressure support and improve the sweep efficiency other than 2T-201 and 2T-217A from the periphery area. Fieldwide recovery and sweep optimization will continue in 2019 as the 2T-209 is brought on injection, and optimal rates are determined between the three injectors. No additional development drilling wells are planned at this time. GKA Annual Surveillance Report Tabasco Oil Pool 108 TARN Pageleftblankintentionally.

Attachment 1 Tarn Oil Pool 2018 Annual Reservoir Surveillance Report Summary of EOR Project and Reservoir Management Summary Background In 1998, Arco Alaska, Inc. received approvals for formation of the Tarn Oil Pool in the Kuparuk River Unit, an Area Injection Order for Tarn, expansion of the Kuparuk River Unit, and formation of the Tarn Participating Area. The Tarn Pool Rules and Area Injection Order were approved on July 21st and July 20th, 1998 respectively. The Unit Expansion and Participating area were approved effective July 1, 1998. Construction of the Tarn road, pads, power lines, and pipelines took place in the 1998-1999 winter construction season. Tarn development drilling commenced in April of 1998. Tarn production began in July 1998, and injection of miscible injectant (MI) began in November 1998. Tarn switched to a miscible water-alternating gas (MWAG) recovery process in July 2001. Progress of EOR Project The permanent 12” water injection line was completed and brought on-line in July 2001. This allowed Tarn to switch from a strictly MI flood to a MWAG recovery process which increases ultimate recovery from the Tarn reservoir. Water injection capacity has been good, and total fluid injection has been able to match reservoir voidage. Through July 2014, the Tarn MWAG process used Kuparuk spec MI injected above the minimum miscibility pressure. Refer to Section 7 of the Kuparuk Annual Surveillance Report for compositional analysis of the Kuparuk spec MI. Following the cessation of imported natural gas liquids from the Prudhoe Bay Field Central Gas Facility at the end of July 2014, immiscible water-alternating gas utilizing lean gas was applied to the Tarn reservoir. Since September 2018, NGL imports from Prudhoe have resumed, thereby enabling the MWAG process to return to Tarn. Reservoir Management Summary In 2018, Tarn produced 2.5 million barrels of oil, 7.3 million barrels of water (MMBW), and 4.8 billion standard cubic feet (BSCF) of gas. The injection totals for 2018 were 2.1 BSCF Lean Gas, 1.9 BSCF Miscible Injectant, and 10.2 MMBW. At the end of 2018, the cumulative injection/withdrawal ratio for Tarn was 1.05. Plans are to continue maintaining reservoir pressure by balancing monthly production and injection rates.

Producer to Injector Conversions No well service conversion projects were executed in Tarn in 2018. Artificial Lift Tarn was originally designed to use miscible gas injection as a means of gas lifting the production wells. However, paraffin deposition in the tubing string occurs when the production fluid temperature falls below the cloud point of 92°F. This is the case of longer reach wells and lower liquid rate production wells. Excessive paraffin build‐up and the high frequency of required paraffin scrapes in some wells led to a change in artificial lift methodology towards surface‐powered downhole jet pumps. In 2001, after successful pilot tests in 1999 and 2000, 13 of the gas lifted wells were converted to jet pump using hot produced water as power fluid. This technique has proven to be very successful in mitigating paraffin deposits. Slickline scrapes and hot oil treatments have been virtually eliminated leading to production increases of about 10%. Unfortunately, the untreated saline produced water injected down the inner annuli (power fluid) has accelerated tubing and casing corrosion. Three well integrity failures occurred on jet‐pumped wells due to both tubing and well casing corrosion in 2006‐ 2007: 2L‐321, 2N‐318, and 2N‐305. These wells were shut‐in and secured. Wells 2N‐305 and 2N‐318 were both sidetracked in 2009. A workover to install an additional casing string was successfully completed for 2L‐ 321 during 2008. In 2009 and 2010, three additional wells were shut‐in after failing mechanical integrity tests: 2N‐319, 2N‐ 303, and 2L‐313. Each of these wells was in jet pump service when the failure occurred. Wells 2N‐319 and 2N‐303 were both sidetracked in 2014, 2L‐313 will likely remain shut‐in and secured until a rotary sidetrack is executed targeting a more prolific area of the reservoir. After water breakthrough occurs in producing wells, paraffin deposition is less likely due to increased well flowing temperatures resulting from the heat capacity of water being greater than that of oil. Consequently, completion designs and alternatives to jet pumps are being considered for new and existing wells. All new producers drilled in 2014‐15 utilized lift gas for artificial lift. In 2016, a mixed approach to artificial lift was adopted. The wells with the highest downtime & cost for paraffin remediation, combined with an expectation of short remaining tubular life were targeted for jet pumps. This resulted in 2L‐330 being converted from gaslift to jet pump, bringing the Tarn total to five active jet pump wells. In 2017 and 2018, the artificial lift strategy has remained largely unchanged. In 2018, the 2N‐304 was converted from surface powered jet pump to gas lift in an effort to reduce water handling costs and corrosion tendency. The well has successfully produced on gas lift with no downtime due to paraffin remediation.

Attachment 1 Torok Oil Pool 2018 Annual Reservoir Surveillance Report Summary of Enhanced Recovery Project Reservoir Management Summary Two new horizontal wells were drilled in 2018, a producer 3S-611 and injector 3S-612. Completion operations were still underway at year-end; the wells will be brought on line in 2019. The producer 3S- 620 and injector 3S-613 are the only Torok wells that operated in 2018. Torok produced 98 thousand barrels (MTSB) of oil, 256 million standard cubic feet (MMSCF) of gas and 316 thousand barrels of water (MBW) during 2018. Over the same period, 748 MBW and 135 MMSCF of lean gas was injected. Cumulative oil, gas, and water production through year-end 2018 were 326 MTSB, 710 MMSCF, and 984 MBW, respectively. Cumulative water injection through year-end 2018 was 1061 MBW; cumulative lean gas injected was 212 MMSCF. The plan is to continue maintaining reservoir pressure operating four wells.

Sincerely, Kazeem Adegbola Manager, GKA Base Production and Optimization Greater Kuparuk Area Pageleftblankintentionally. Attachment 1 West Sak Oil Pool 2018 Annual Reservoir Surveillance Report Summary of the Enhanced Oil Recovery Project During 2018, there were fifty‐seven (57) active producers and fifty‐four (54) active injectors, including six (6) water‐alternating‐gas injectors and forty‐eight (48) water injectors, in the West Sak Oil Pool. Waterflood continues to be the primary method to improve oil recovery and maintain reservoir pressure at West Sak. Water is sourced from the Seawater Treatment Plant (STP) and the Central Processing Facility (CPF‐1). Injection and production performance in the West Sak Oil Pool is challenged by matrix bypass events (MBEs) or highly conductive conduits between an injector and a producer. These conduits effectively short‐circuit the waterflood resulting in poor pattern sweep without remediation. During 2018, four new MBEs developed at 1J‐ 154, 1J‐164, 1E‐114, and 3K‐103 During 2018, six MBE remediation treatments were attempted in injectors 1E‐105, 1J‐154, 1J‐170, 1J‐164, 1J‐136 and 1E‐105 to reestablish water injection support and pattern sweep. Three of the six treatments failed before the end of 2018. A review of these failures is underway as well as an evaluation of alternative treatment methodologies. In 2014, the AOGCC approved Viscosity Reducing Water‐Alternating Gas (VRWAG) injection as an enhanced oil recovery process for the West Sak Oil Pool. Injectors 1C‐150, 1C‐152, 1C‐154, 1D‐142, 1E‐117 and 1J‐122 received VRI injection during 2018. Early results of VRWAG suggest positive benefits and pattern‐level surveillance efforts continue.

During 2018, the annualized average gas offtake was 1,931 MSCFD, considerably less than the maximum allowable annual average gas offtake rate of 5,000 MSCFD as stated in Rule 13 for Kuparuk River Oil Pool. The low annualized average gas offtake was driven by Oooguruk s gas production, which now exceeds their injection and fuel consumption, resulting in taking only their return gas and no makeup for fuel. If you have any questions concerning this data, please contact Kazeem Adegbola at (907) 263-4027. Sincerely, Kazeem Adegbola Manager, GKA Base Production and Optimization Greater Kuparuk Area Pageleftblankintentionally.
